Title: Method and apparatus for removing an imperfect intermediate portion of a web
IPC: D06H7/02
Filed: 1973-09-19
Abstract: 1436778 Cutting apparatus EASTMAN KODAK CO 19 Sept 1973 [20 Sept 1972] 43947/73 Heading B4B [Also in Division G2]  A method of removing an imperfect portion from a continuous web comprises transporting the web along a first path and severing it on one side of the imperfect portion to form a first web end portion, transporting that part of the web containing the imperfect portion along a second path and severing it on the other side of the imperfect portion to form a second web end portion and returning the web in the second path to the first path so that the two web ends can be spliced together. In the apparatus for carrying out the method rollers 12 transport the web 10 along the first path defined by a trap door 20 and bed 40. A blade 30 mounted in a pivotable holder 26 is moved clockwise and co-operates with a stationary blade 16 to sever the web on one side of the imperfect portion, leaving a web end 15. The holder 26 also carries a lever 54 having a hook 52 and shoulder 64. The hook engages with a spring finger 56 on the trap door 20 and as the holder pivots clockwise the lever moves down allowing the trap door to fall under its own weight until it engages a resiliently mounted roller 60 so that after the web is severed that part of the web having the imperfect portion is guided between blade 16 and a second stationary blade 18. The web is transported until the imperfect portion is fully received in the channel, blade 32 is then fully depressed to sever the web leaving a web end 22. At this stage the hook 52 is completely disengaged from the finger 56. As the holder 26 is raised the shoulder 64 of the lever engages the finger 56, raising up the trap door which in turn lifts the severed web portion so that the ends 15, 22 overlap in the first path ready for splicing by the ultrasonic horn 24. The holder 26 is operated by an air cylinder 36 and the blade 32 may be moved rapidly past blade 18 while the imperfect portion is being transported through the channel to sever this portion into small units.

In a microwave header supporting a semiconductor device said header comprises a ceramic disc having a metallized coating on at least one surface thereof and a plurality of leads secured to the disc and connected by regions of the metallized coating to the device, the leads and part of the metallic coating forming a matched impedance terminating network of the device. A ceramic disc 10 has metallized portions 14, 15 and 16 thereon each portion being connected by a pin 13, 11 and 17 respectively to corresponding metallized portions (22, 21 and 27, Fig. 1d, not shown) on the reverse side of the disc. A transistor 32 is mounted on portion 14 and has double electrode connections from portions 15 and 16 (Fig. 1e, not shown). Leads 28, 29 and 30 are provided to the metallized portions on the reverse side of the disc. A metallic ring (38) and a metallic disc (39) are hermetically sealed to the upper face of the disc (Fig. 2, not shown). The configuration and relationship of the metallized portions 14, 15 and 16 and those on the reverse side of the disc (21, 22 and 27) are designed to minimize the parasitic capacitance and inductance associated with the encapsulated transistor, an equivalent circuit of the device and header being given (Fig. 3, not shown). The characteristic impedance of the header may be evaluated in a VSWR test, by bridging the gap between the metallized portions 14 and 16. Since the metallized portions are laid down by a silk screening technique the area and shape of the portions may be easily changed and hence the impedance of the header.

Abstract: 1,206,284. Extracting crop from a heap or mass. E. WEICHEL. 2 Oct., 1967 [3 Oct., 1966], No. 44681/67. Heading A4C. In a machine for gradually breaking up a rotating mass of cereal or leaf crop and then conveying the separated material away, a rotating turntable 103 is secured to a frame 101, on which a vertical column 104 is secured outside the orbital track of the outer edge of the turntable and to which the greater part of the defining wall 122 is rigidly connected. Rotating fixed or movable tines 109 or cutting elements, which are mounted on a shaft 108 at the free end of a carrying pivotable frame 106, sever and tear the material and throw it towards the outer edge of turntable 103 along a tunnel 117 into the receiving trough of a conveyer 124 or against a fixed rebound plate 121 from which the commodity falls back into the receiving trough of the conveyer 124. The tunnel 117 is supported on a retaining arm 120 secured to the carrying frame 106 and terminating in a pivotal point 127 advantageously arranged concentrically to the cutter shaft 108. In every position of the cutter shaft 108, the tunnel 117 maintains substantially the same radial position relative to the orbit of the cutters 109, and the same vertical distance relative to the surface of the turntable which is driven via a variable speed gear. A spindle 114 co-operating with a spindle nut 115 pivotally secured to the frame 101 engaging on a bracket 125 mounted on the upper edge of the carrying frame 106 ensures that the carrying frame 106 may be pivoted continuously or intermittently about the column 104, so that during the cutting operation the cutters 109 can adapt themselves to the continuously reducing diameter of the mass. The separating device 108, 109 gradually moves to the centre of the turntable 103 during the breaking-up process. The carrying frame may also be subjected to the action of a tension spring drawing it inwardly in a similar direction as the spindle 114. Alternative cutting elements are cutter rollers or a centrifugal roller having a substantially vertical axle, reciprocating cutters, or vertically and or horizontally disposed cutting discs.
